`.Application led April 25,

Our device relates to dust bins and has' for its primary object thereception and retention of sweeping-s and the like, the same being madeof metallic sheets having a hinged closure disposed adjacent the frontwall thereof and having a bin or chute disposed adjacent to or formingthe inner bottom wall of the body element.

The primary purpose and object of our de- ,o vice is to displace orreplace dust pans and the lilre and is intended for placingwithini asimplified `construction that may be used' to conduct the sweepings fromthe various rooms to a central receptacle that may be disposed withinthe furnace or within the basenient of the house or building in whichthe same are being used.

A further object of our invention is to provide a means that will speedup the sweepthe use of dust pans and'wherein the sweeping refuse may bedeposited within a suitable receptacle or collected at a centralstation.

lilith these and incidental objects inview,

i the invention consists in certain novel fea-1V tures of constructionand combination of parts, the essential elements of which are set forthin the appended claims, and a preferred form of embodiment of which ishereina fter shown with reference to the drawings that accompany andform a part of this specification.

We preferably form our device of sheet bars for the body 'element 10; VAhinged closure l2 is hingedly supported upon a j ournaled pin V13,vsupported in oppositely disposed ends of the body portion 10. The I5hinging closure l2 is adapted to being actuated by the 'foot or'handv ofthejsweeper or manipulated by the'broomor sweeping irn-` plement. A!locking bar 11i ishinged relative to the side wall about a hinging pin15. One end 20 of the locking bar 14 passesthrough a slot 16 andprotrudes 'therefromso that it may be actuated by any suitable means. VAlocking notch 17 is disposedgon the other endA 'of the lockingbar 14.'The locking bar 14 isA pivoted olf-center upon vthe pin 2l so that thelockingbar rides upon the pin 18 secured `uponthe hinged closurel.v Whenit is deso that the locking notch 17 catches on pin 21 and by gravitythe bar 14 stays in position until a downward pressure is applied to theprotruding end 20; the closure then will return to that of the normalclosed position through the action of gravity. An arcuate slot 19 isdisposed within the side of the body element through which the pin 18passes. The sides of the body element have lo inwardly extending edges21B which act as supports for the dust bin 21 which is removably,disposed upon. the base ofthe bodyy element,; said bin havingoutwardlyextending iaps 21C which ride on edges 21B.

There a positive closure is desired an actuating-:spring 121A. may `bevplaced about Athe hinging pin 13 to snap the closure 12 shut. Where ourdevice is to be installed in new construction, dust chutesor sweepingchutes 20 lead from the receptacle to a central collector disposed at aconvenient .location in the basement or running directly to the-furnaceso :u that the sweepings may be collected at a cen- .E trallstation e525Then it is desired toremove thesweepings 'i f fthe door is -lopened:andth-e bin 21- is removed through the opening as illustratedl inFig..4. i VVhi-le .the fformof `mechanism herein shown and describedisfadmirably adapted to .230 ulllthe obj ects` primarilystated; it is tobe gunderstoodfthat it islnotfi-ntended to confine g, the inventiontofthe one-'form' of;embo'cli ment herein-shown, as it, is susceptibleof embodiment in various formsT Aall comingwithin m35 fthe scope ofthe-claims whichfollow.
